Rhizome wide-creeping. Stipes about 30 c.M. long, erect, villose, clothed 

 at tlie base with squarrose, linear scales. Fronds 45 — 60 c.M. long, 30 

 c.M. or more broad, deltoid. Lower pinnae much the largest, 7 — ^15 c.M. 

 broad. Pinnulae of Ihe lowest side the largest, often 12 '/2 c.M. long, to 5 

 c.M. broad, with distinct, lanceolate segments. Segments decurrent, with 

 close, entire or slightly toothed, acute, linear-oblong lobes. Texture firm; 

 rachises villose; under surface naked or villose. Sori small, 6 — ^8 round the 

 edge of the larger lobes.

Rhizome wide-creeping, stout, densely fibrillose. Stipes ± 1.5 c.M. long, 

 firm, erect, brown, naked. Fronds 30 — 45 c.M. long, 10—15 c.M. broad, 

 lanceolate. Pinnae 5 — 8 c.M. long, 2 — 2 ^j^ c.M. broad, cut down to a broadly 

 winged rachis into linear-oblong, deeply pinnatifid lobes. Texture subcoriaceous; 

 rachis and veins beneath finely villose; veins about 6 on a side. Sori ± 

 midway on the veins ; indusium coriaceous, persistent. — Habit of D. flaccida, 

 0. Ktze, but different in texture and mode of growth, in which it approxi-

Stipes tufted, 10 — 15 c.M. long, densely clothed with fibrillose scales. 

 Fronds 30 — 45 c.M. long, 15 — 25 c.M. broad. Lowest pinnae largest, 

 deltoid, 5 — 8 c.M. broad. Pinnulae lanceolate, 5 '/2 — S c.M. long, cut down to 

 the rachis below into erecto-patent, entire, linear segments. Texture herba- 

 ceous : rachises densely fibrillose ; both surfaces naked ; veins of the segments 

 5 — 6 on a side, the lower ones forked. Sori in a line close to the coslulae.
